“…In order to provide for internal consistency of the properties of saturated and superheated vapor and to estimate the reliability of the pvT-data, it is of fundamental importance that the experimental data on the saturation pressure p s -T s [33][34][35][36][37][38][39][40][41] should be included in simultaneous statistical treatment. Of the generally available p s -T s -data for rubidium [9,[13][14][15], Table 3 gives the data obtained using mercury or piston pressure gages.…”

Statistical matching is performed of a wide range of diverse experimental data on the thermodynamic properties of saturated and superheated rubidium vapors at temperatures up to 1650 K. The parametric models used in the matching of data include the equation of state in the virial form and equations in the form of group expansions in terms of degrees of activity. Values of the second virial and group coefficients are obtained using new spectroscopic data on the singlet potential of rubidium atoms in the ground electron state. The equation of state in the form of expansion of density in terms of degrees of activity is used to calculate the tables of thermodynamic functions and estimate their confidence errors at temperatures up to 1600 K and pressures up to 4 MPa.

“…Kallenbach and Kock [13] report a value of 8 10 −14 cm 2 , Bowen and Thorn [11] find (6±2) 10 −14 cm 2 whereas Bokkam [20] reported a value of (3.9 ± 0.5) 10 −16 cm 2 . Finally, from the work of Eversole and Djeu [1] it is possible to give an estimate of the cross section considering the quenching rate that they measured at zero buffer gas pressure and calculating the corresponding barium density using the formula of Bohdansky and Schins [21]. In this way we obtain ≈ 1 10 −14 cm 2 .…”
